lfor use in inking rubber stamps and the like.'I The principal objects of the jinvention are to provide adevice of this.` character which vwill be durable; which will not scratch a .deslror table on which itis used, and which will be entirely noiseless and will have a neat appearance leven after it lhas been used for a long time; also 4to provide a construction in which the 4base vblock that insures certain of the above Vnamed l,advantages is so covered as to 4avoid the projection of metal- 'provide a no'ncollapsible j:top that will not "lic edges and -willalso constitute a flatsurfface' against whichthe llower edge Ioff the cover will'rest whenthe box is closed; to

' jani down over-*the sides of the pad even with'the roughest'usag'e; y'to 4provide .af-n iinproved way c of "co'verang and concealing `the internal support and providing a nea-t inetal-V lic covering; and'to provide improved vmeans for securing fthe h1nges ofthe cove-r to the base vblock.` j v vFurther objects and advantages off-the '1n-1' vention will appear hereinafter; l

Reference isfto 'be 'had'to the accompanys Fig. 1 is ya 'perspective view of a stamp pa'd'bo'x and oever constructed in accordance with this invention and shown open; v

Fig. 3 is a longitudinal rsectional view showing the 4'padin use 'and takenon the 'line Fig. 4 is a transverse sectional 'ing the box closed 'and taken' on 'the gline 1 -4 of Figrl.` A y An important feature of the vinvention consists inthe use of Iav'bvase 10 formed of wood fiber board cu't to-"the proper shape. On this base is fixed a plate 13 also of fiber board of the samevshape as the base but sfn'aller each way. These two pieces of fiber board are firmly Xed together. Over this is a covering 1l of sheet metal, Celluloid, or

the like which is formed with a topwhich is i pressed out to'fa rectangular shape and lhas y into, a yhigher `plane around, a ycentral -openingkfQ ofthe saine general shape as the liber board base.

The opening 12 'is smaller in each diinension its fcentral portion 16 raised` than the plate y'13 sothat it affords a firm yfound-ation for the flat upper partflhjof the covering 11. The upper'pilate 13 'fills the' opening inthe covering ll'fand ,consti-tutes' fa surface 'to which the inking padZOcan -be glued vor otherwise secl'rred. v

The Vinlring pad Aconsists of apiece of sponge rubber sp'l'it `in twovso as 'to provide lan uppersu'rface of split sponge rubbertjand fa bottoni 1skin .surface which is coinj'iara V"tively lfree from even minute openingsand iscapable of' being cemented or yglued, tothe `base plate. it projects over the edges of the opening 12 all around and conceals 'those edges fromA view. r The'covering .11' Iis held .in position on the base by 'flanges 17 which :extend down ati-ight angles tothe plane of the sidesandv ends of the baseiO.

the top thereof :and tfr'iction'ally against thereof and projecting beyond the rear'edge l,of the opening` are a vpair of lsheet` inetal hinge v'members through cylindricalfopenings '23 in lthe I)bottoin edge ofa sheet InetalA cover 24.l This l,cover is larger than the inlring pad and in useits vside and end `flanges rest yon the upper horizontal "surface 16 of* Athe covering '11.'

i There is no chance 'for these flangesofthis cover pressing 'out over thebox, or,` getting out of'shape y1n use.,4 It 1s for this reason :that I call it anon-collapsible top. view Qshow on account ofthe mangiar which the base is made the device incapableWof lScraftching al desk' en which' it is :used and it is noiselessl in use as it hasno 'nietal parts adapted tol come into contact with the surface on which it is supported. The'sponge.y

rubber pad and "the wood 4ber board are cemented directly togetherand one o'flthese two eleinents comes "on either lside of the Inetal or Celluloid covering 11 so as to hold the latter rmly in position. On account of Iao Lying o'vervthe coveringf'llfat vthe back ilo j 'l the direct binding between the sponge rubber and the base board there will be no noise when the device is used for inking purposes because the rubber pad itself is supported firmly and without possibility of movement from the support-ing base. rllhis is an important feature because in the ordinary tin box pads a bulging of the sides of the tin is noticeable when the rubber stamp is pressed against the pad. This is due to the air pocket or space which develops a noise when the pad is hit with the rubber stamp.

.The way of securing` the hinged cover to the base board is important because it will be seen that all parts, that is, the cover, the rubber pad and the cover ll, are directly carried by one element, the base. The ledge .16 around the rubber pad is supported j firmly below and receives the lower edge of thecover when closed. As this is a hori- Zontal surface it will not cause the edgesof the cover, consisting of four downwardly extending flanges to diverge from each other when the cover is accidentally pressed down too hard. Furthermore, there is no chance of these flanges engaging any vertical surface and sticking or binding as is-common with the ordinary tin boxes on the market.

On account of the ,usev of the sponge rubber for the pad it is not necessary to close` the box absolutely tightly as has been the casewith the rordinary rubber pads. rlhis is due to the fact that in comparative tests, the ordinary rubber stamp pad has had a life of about fifty thousand. impressions while a j porous rubber pad of. this kind will stand overv a million and a half impressions without showing any serious signs of wear. The device is not seriously affected by dust in any form and there is no danger of the ink Lcoming out because the rubber pad itselfim- ,mediately draws backany that comes to the surfacev when the pressure of therubber stamp is removed from it.

Although I have illustrated and described only one f-o-rm of the invention I am awarevr LTof thefact that modifications can be made :therein by any person skilled in the art without departing from the scope of the invention as expressed in the claims. Therefore I, do not wish to be limited to all the details of construction herein shown and.

7described but what l do claim iszl. As an article of manufacture, a stamp pad box comprising a base of wood fiber, a covering over the edges and around the perimeter of the top thereof and having an opening therethrough, and a stamp pad'in onepiece firmly secured through said openingV to the fiber board base ,andy projecting .4 over lthe edges of said opening to conceal the Same.

medals pad box comprising a base of wood fiber board, a sheet metal covering over the top thereof having ianges extending around the sides and ends of the base but of less width than the depth of the base to prevent their contact with a supporting surface, and having an opening therethrough, and a stamp pad secured through said opening to the iiber board base.

3. an article of manufacture, a stamp pad box comprising a non-metallic base having a central portion projecting above the main portion and spaced equally around the edges thereof, a covering of` sheet material around the edges of both portions and having an opening therethrough, and a pad of sponge rubber secured tothe upper portion of the base through said opening and projecting over the edges of the opening to conceal the same.

4l. its an article of manufacture, a stamp pad box comprising a wood fiber board base having a central plate projecting above the main portion and spaced equally around the edges thereof, a coveringor` sheet material having a raised flat surface resting on the edges of said plate and having a rectangular slanting surface extending around the edges of both portions and having an opening through said raised surface and a pad .of

sponge rubber cemented to the upper portion ofthe base through said opening. v

5'. As an article of manufacture, a stamp pad box 'comprising a non-metallic base, a covering of sheet materialaround the edges thereof and havingan opening therethrough, a pad of sponge rubber secured tothe top of the base through said opening and pro- .jecting over the edges of the opening to conceal the same, hinge pieces of sheet material secured to the fiber base board and extending over thek covering,r at the -rear thereof, and a cover of sheet/material hinged to said hinge pieces and adapted to rest on the horizontal upper surface o-f said covering.

6. In a stamp pad box, thecombination with a fiber board base yhaving a central portion projecting above the main portion and spaced equally around the-edges thereof, a

covering of sheet material around they edges of both portions and having an opening therethrough, a pad` of sponge rubber secured to the upper portion of the basek through said opening, hingel pieces of sheet material secured tothe fiber base board and,

projecting over the cover at the rear thereof, and a cover of sheet material hinged to said hinge pieces and adapted to rest on the horizontal upper surface of said covering.

In testimony whereof I have hereunto affixed by signature.
